JAMES A. MORE AND LEWIS GRUBE, OF LOWER SAUCON, PENNSYLVANIA.

SPECIFICATION forming part of Letters Patent No. 250,566, dated December 6, 1881.

Application filed September 12, 188].

1o enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specication.

Our invention relates to automatic sledbrakes; and itconsists in the construction and arrangement of its several parts, as will be hereinafter fully explained.

The accompanying drawings fully illustrate zo our invention, Figure 1 being aside view, and

Fig. 2 a plan of the same. Y

A is a sled of ordinary construction, having runners a, stanchions c', cross-braces a2, and side braces, a3, as shown.

Bis the tongue. It passes through a hole in the foward brace, and its innerend eutersaslot in the second brace. Ithas pivoted toit the inner end of the brake-lever b, which is also pivoted to the bar bl, and has pivoted to its outer 3o end the connecting-rod c, as shown.

Hinged to the back brace, o2, is the brakebar d, having rods df, to which are pivoted the horizontal brake-pins e, which may pass through runners or be held by suitable means upon their ends or sides, as shown.

To either end of the brake-bar d is secured (No model.)

the crankf, which has pivoted to it the connecting-rod c, as shown.

g is the brake-stop. It passes through a hole in the side brace, a3, rests on a hanger placed on the forward brace, a?, as shown, and prevents the automatic action of the brake, when desired.

To render the brake operative it is necessary only to Withdrawv the brake-stop from the recess.

In the operation of my brake it will be seen that when the sled descends a hill the resistance of the tongue forces it backward, carrying with it the brake-lever b, connecting-rod c, crank j', and brake-bar d,which operates to force the brake-pins e down into the snow and stop or impede the sled.

We do not confine ourselves to the application and operation ofthe device upon one side ofthe sled, but provide that when heavy grades are encountered or heavyloads hauled the operating device may be placed upon both sides, the brake-levers b crossing each other under the tongue B.

What We claim is- In a sled-brake, the lever b, pivoted to the lug b', secured to the brace c2, operating, in combination with the tongue B and stop g, substantially as shown and described.

In testimony whereof' we atlx oursignatures in presence of two witnesses.
